"l y Bei` 'tu known ,that I, CHARLES G. "Cmiris, ofjSpringfield,"in the* county of Hampden and@ Stateof `Massachu'setts,` have invented a new and useful Improvement in the Double- Action: Forcing l and" Lifting Pump; and "I doi` hereby declare ythat the same is `fully de- 1 scribed andwrepresented in the following 3 p r i, f specification `and the accompanying drawp p Of the said drawings,Figure 1, denotesa vside` elevation of my improved pumpgFig. 2, is avertical sectioneoflit taken through the induction and eduction pipes; Fig. 3 is a verticalsection` of it taken through `the pipe ings, letters, figures, and references thereof.

that leadsupward out offthe lower. end of the pump barrel; FigLA, is a top `view of "fthe valve chambers, and valves asthey ap- "pear when the cover plate of the pump is i `section `taken `through Ithe induction and leading chambers which are disposed under Vthevalve chambers.

removedfrom them. i Fig. 5 is a-horizontal A, in the said drawings exhibits the pump barrel which is closed at its lower end by being fastened to a supporting plate, I. Ar-

' ranged concentrically around and `near to the upper end of the pumpbarrel is an annular space-whichby means of three parti-` tions a, I), 0 radiating `from the barrel, is

" f j dividedinto` three chambers, C, D, and E,

i the first of them being what may be termed the induction chamber while the other i two may becalled leading chambers? Directly over the said annularspace and disposed Vcoricentrically around the upper'end of the pump `barrel is another annular space, 1 `which by means of three partitions e, f, g, 1s

= f `divided into three valve chambers, F, G, H.

` would remarkthat `the partition g, is

placed over and between thetwo partitions b, and c. The partition e, is also placed above and betweenthe twofpartitions a, and b. In regardtoythe partition f, it is ar.

ranged above and ,between the two partitions a, and c.

` The leading chambers, D, and E, respec` tivelycommunicate with the valve chambers F, and G, byfmeans of passages `as seen at... h., z', `formed through the bottoms of Said f chambers F, andlG. The `induction cham-1 ber, C, communicates withboth the chambers F and G, by means of valve passages, to which valves are adapted as seen at 7c, Z, saidv valves, being made to open upward. Within l the induction chamber, H, there `are two lead intofthe leading chambers D, E, said valve chamber, H, not only having its Valve made to open upward, but having a "dischargepipeK, leading outof it. vThe induction pipe, B, by which water or fluid is in# `troduced toth` pump is made to enter the induction chamber,

The upper part of the pump barrel iis-'connected-i `with the leading chamber `by means of a passage, L, as seen in Figs. 2, 3, and 5, while the lower artof said `pump barrel has apipeM, lea ing out of it, and made at its upper endf to open intothe leading chamber E. `A. single circular cap plate, N, suffices to cover the valve chambers, F, G, and H, and the top of the barrel, A, said cap vplate being provided with a stuiiing box, O, through which the piston rod of the piston,f

P, plays. One circular washer (m) of leather serves to pack the joints of the cap plate and the partitions directly underneath it. An air vessel, R, may be aiiiXed on the cap plate N, and made to communicate with the valve chamber H. When the lower end of the pipe, B, is in communication with a reservoir of water, if the piston of the pump is raised the water will be made to iiow into the induction chamber, C, and froml thence through the opening of the valve, Z,

into the valve chamber, G, thence down the passage, z', and into the leading chamber, E,

thence down through the pipe M, into that partuof the pump barrel which is below the piston. When the piston is next forced downward, the valve, l, will be closed upon itsseat `and the. water will be forced out of `the pump barrel up through the pipe M, into `the leading chamber, E, and from thence up through the valve passage n into the eduction chamber, H, whose valve, n, will be closedin the meantime. During the depression of the piston,l the valve c,will be raised andthe water wil pass from the induction chamber, C, through the passage of said valve', c, and into the chamber F, from whence it `will pass downward through the opening, h, and into the leading chamber, D,

andthence will How through the opening L, into that `part of the barrel, A, which is above the piston. Now on the piston being elevated, the water will be drawn out of the upper part ofthe barrel and will pass throughthe passage, L, ntothechamber D, and will close the valve lc, and open the valve lm, and pass into the `eduction chamber, H,

"valves, m, n, whose passages respectively A the water being driven from-such through its induction pipe, K.

I am aware that induction and eduction valve chambers and valves with their case, have been arranged on the side of a horizontal pump barrel and midway between its two ends, the barrel being made to communicate with the valve case by two pipes leading from said case respectively into the two ends of such barrel. I am also aware that valves and their chambers have been placed a-t the lower end of a vertical pump barrel and a leading pipe used to connect the valve case with vthe upper part of the pump barrel; the first of these arrangements only requires the removal of a cover plate to obtain access to I the valves (such cover plate having vno connection with or forming port of the cover plate of the end of the barrel) while the second of these arrangements rendered it necessary to raise from the valve case the whole pump barrel and cap plate of the valve case in order to obtain access to the valves.

I therefore do not claim either of such arrangements, my invention having reference to an upright pump barrel, but

What I do claim is Arranging the eduction and induction CHARLES G. CURTIS.
